Can blueberry plant cross pollinate with blackberries plant ? Would it make my blueberry plant give out a lot of blueberries ?

No, generally cross pollitation is limited to varieties of the same species. In the case of blackberries (Rubus) and blueberries (Vaccinium), they are not even the same genus. To improve set of blueberry bushes, you need other varieties of blueberries that bloom at the same time as the varieties you already have.
Thank you for you honest answer.
